---------------------------------------------------------------------------
KNOWN PROBLEMS:

country code
	- The firmware of the chip needs the country code to determine
	the stardards of video and audio when it runs for analog TV or radio.
	The DVB-T does not need the country code.

	So you must set the country-code correctly. The V4L2 does not have
	the interface,the driver has to provide a parameter `country_code'.

	You could set the coutry code in two ways, take USA as example
	(The USA's country code is 1):

	[1] add the following line in /etc/modprobe.conf before you insert the
	    card into USB hub's port :
		poseidon country_code=1

	[2] You can also modify the parameter at runtime (before you run the
	    application such as VLC)
		#echo 1 > /sys/module/poseidon/parameter/country_code
